I am sick of inhaling melted plastic from burning air holes in tubs. I have wanted one of these for a long time. I'd like to pick one up in the next week or so.

In addition to drilling holes, I'd like to have as many applications available from my Dremel while keeping costs as low as possible.

Should I just buy the Dremel and add pieces later, or buy a package? I prefer to have a cord, I always run out of batteries at the worst time. I have an Amazon prime account so that might save me some money.
